    Abstract : Habitat degradation, fragmentation and loss are important factors causing loss in biodiversity and red listed species, and restoring habitats is essential in preventing this. However, there is a limited knowledge of the long term effects of restoration measures. READ MORE

  3. 7. Differences in plant trait distribution in semi-natural grassland habitats of Sweden

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Viivi Vepsäläinen; [2020]
    Keywords : Plant traits; semi-natural grassland habitats; landscape openness; landscape ecology;

    Abstract : Habitat type has been suggested to be a major factor contributing to differencesin plant trait distribution of grassland habitats. Land use changes in agricultural landscapes have affected the available habitats and the dispersal ability of plants, which may effect plant trait diversity of agricultural landscapes. READ MORE

  4. 8. The effect of the interplay between fire frequency and grassland structure on tick abundances in the Hluhluwe-iMfolozi Park, South Africa

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Thilo Heinecke; [2020]
    Keywords : ticks; acari; pyrodiversity; grassland structure; fire ecology; fire frequency; grazing lawn;

    Abstract : Fire in ecology is a very variable factor and its effects are best described as a complex feedback system with other biotic and abiotic factors. These feedback systems need to be understood to enable generalized conclusions about the influence of fire regimes. READ MORE

  5. 9. The Journey of Resources : Archaeobotanical analysis of late Iron Age and medieval Sigtuna, Sweden

    University essay from Uppsala universitet/Institutionen för arkeologi och antik historia

    Author : Siri Pettersson; [2019]
    Keywords : agricultural history; archaeobotany; archaeology; continuity; ecology; grassland ecology; historical ecology; history; Iron Age; landscape management; land use; land use tradition; medieval period; middle ages; niche construction; paleoecology; plant ecology; Professorn; resource ecology; Sigtuna; traditional landscape management; Carex; Cyperaceae;

    Abstract : Traditional agriculture has played an important role in shaping the landscape for thousands of years. Agriculture and interactions between humans and their surroundings have changed since the beginning of historic time in Sweden, approximately 1000 years ago. READ MORE

  6. 10. Effect of restoration and surrounding grassland proportion on the dung beetle metapopulation abundance in the fragmented semi-natural grasslands : dung beetles in restored semi-natural grasslands

    University essay from SLU/Dept. of Ecology

    Author : Vivek Babu; [2018]
    Keywords : dung beetle; grassland proportion; restoration; Aphodius; Geotrupes; abundance; semi-natural grassland; Scarabaeidae; metapopulation; habitat fragmentation; landscape ecology;

    Abstract : The importance of landscape composition surrounding the local habitats is increasingly recognized, especially with goal of enhancing the understanding about its role in various conservation frameworks. The dung beetles which depend on human mediated ephemeral resources (Dung from domestic animal) gives a valuable opportunity for understanding landscape moderated effects of both the landscape structure as well as sensitive grazing management on the local populations of semi-natural grasslands in Sweden.
